In practical use of the present invention, the can opening device 10 is attached to a suitable supporting wall or other supporting structure 29 with pivotal member 30 in normally angular relation and the laterally extending arm 54 in perpendicular relation to the pivotal member 30. A can is positioned with the bottom thereon on the ledge 104 and the can 79 is pushed inwardly thereby pivoting the pivotal member 30 about the pivot pin 32 so that it moves toward the front surface of the bracket 12. By pivotingthe arm 5d downwardly and sliding the mounting of the sliding lug d6 vertically, the pin portion 72 of the arm 54 may be positioned in any of the selective notches 74 thereby vertically adjusting the arm 54 for accommodating cans of various heights ,or lengths. By adjusting the pointed punch 66 in the guide 62, the distance .between the punches 58 and 66 may be adjusted thereby accommodating cans of various diameters. As the can 70 along with the pivotalmernber 30 is moved inwardly, the interconnecting link 93 moving about its pivotal connection plate 92, the ledge 104 and the can 76 upwardly and longitudinally along the pivotal member 39 until they contact and pass over and onto the punch membersSS and 66 thereby punching two diametrically opposed holes in the upper end of the can 7%. As the can 70 and the pivotal member 36 moves to inner limit of movement, the projection 198 passes through the opening106 in the plate 92 and engages the periphery of the can 70 adjacent the lower end thereof thereby refrom the ledge 104 70 to be pulled downwardly off for permitting the can thereby forming an of the punch members 58 and 66 easily operating can opening device.

When it is desired to collapse the can opening device 10 of the present invention to an out-of-the-way position, the punch member 66 is movedinwardly to its inner limit of movement and the arm 54 pivoted downwardly so that the punch members 58 and 66 will pass through the enlarged slot 88 and be positioned in the recessed portion 22 After the arm 54 has been pivoted downwardly, wardly wherein the plate 92 will slide upwardly for engaging the hook 116 with the notch 86 in the outer end of the arm 54 thereby automatically locking the arm 54 to the pivotal member 30. After the pivotal member 30 is moved to its innermost position, the manual latch 116 is moved upwardly into the notch 114 in the outer surface of the channel shaped member 42 by utilizing the handle member-.118 thereby securely positioning the pivotal member30 and the arm 54 in collapsed position. When it is.

operating position and the can opening device 10 is then ready :for use. It will be seen that the device of the preseut invention is especially useful in opening a plurality of cans that contain liquids or only necessary to-punch a pair holes in the top thereof.

Referring now specifically seen that the numeral 120 generally indicates the modified and simplified form of the can opener of the present inve'ntion. The form of the invention as illustrated in Figures 9-12 includes a fiat supporting bracket 122 having apertures 124 therein for receiving mounting screws. At the upper end of the bracket 122 is pivotally mounted a channelshaped pivotal member 126 by pivot pin 128. An axial spring surrounds the pivot pin 128 and is. disposed with one end against the forward surface of the of diametrically opposed 96 and .162 will move the sliding semi-liquids wherein it is.

to Figures 9-12, it will be 7 bracket 122 and one end against the rear surface of the channel shaped pivotal member 126 thereby urging the channel shaped pivotal member 126 outwardly to a normally depending angular relation to the vertically disposed bracket 122. Rigidly secured to the upper end and projecting laterally outwardly therefrom is an arm 132 having a depending angulated punch member 134 on the outer end thereof and a depending generally triangular punch member 136 on the inner end thereof having a flat face 138 for punching two diametrically opposed openings in the top of a can 140. The lower end of the channel shaped member 126 is provided with an elongated and enlarged slot 142 for slidably receiving a plate 146 having inwardly extending grooves 148 in the opposite longitudinal edges thereof wherein the grooves 148 slidably receive the portions of the channel shaped member 126 which forms the edges of the slot 142, thereby slidably guiding the plate 146 on the pivotal member 126. The lower end of the plate 146 is provided with an inwardly extending ledge 150 for engaging under the bottom of the can 149. The upper end of the plate 146 is pivotally connected to an interconnecting link 152 by pivot pin 154 and the other end of the link 152 is connected adjacent the bottom of the bracket 122 by pivot pin 156. it will be seen that by inward pivotal movement of the pivotal member 126, the plate or can holding member 146 will be moved longitudinally in relation to the pivotal member 126 thereby moving the can holding ledge 150 towards the punch members 136 and 134 for punching diametrically opposed holes in the top of the can 140 when the pivotal member 126 is urged inwardly. It will be noted that the forward surface of the bracket 122 is provided with pivot lugs 158 on opposite edges thereof for receiving the pivot pin 156 which extends through the bottom end of the interconnecting link 152. Secured to and integrally formed with the interconnecting link 152 is a pair of outwardly or forwardly projecting legs 160 which bridge each side of the channel shaped pivotal member 126 for engaging the periphery of the can 140 adjacent the pivotal member when the pivotal member 126 and the can 140 are moved inwardly substantially alongside and coextensive to the bracket 122. The operation of this form of the invention is the same as that form illustrated in Figures 1-8 and is substantially the same except that it is formed in a more simplified nature thereby reducing the manufacturing cost to an absolute minimum.

in boLh forms of the invention, the can to be opened is merely positioned on a can supporting ledge 104 or 150 and the can pivoted inwardly along with the pivotal memiii bers 36 or 126 thereby engaging the top of the can onto the punch members 66, 58 or 134, 136, thereby punching diametrically opposed holes in the top of the can. After each operation, the can opening device 10 or 120 returns to its normal can receiving position wherein another can may be easily inserted therein for opening. Also, the projection 198 or the projecting leg 160 will quickly disengage the can from the can engaging ledge 104 or 150 thereby permitting easy and rapid removal of the can from the can opening device 10 or 120. In each case, the device represents an easily and efficiently used can opening device wherein a person opening a can may do so utilizing only one hand while the other hand holds another can to be opened or for performing any other function. The device is especially useful in opening cans of liquid wherein a plurality of cans must be opened in a relatively short time such as in places serving the public liquids of any nature that are normally packaged and delivered in cans or similar container be constructed or" any suitable material that is attractive for use in homes, restaurants, bars or the like, and which will be relatively light and inexpensive wherein the device may be constructed utilizing well known manufacturing procedures thereby holding the manufacturing and 126 and adjacent the ledge 150 Obviously, the device may 6 resultant sale price to a It will be noted that the groove in the punch members 58 and 136 permit escape of air from the can as it is being punched thereby preventing the liquid from spurting out as the punches are pressed into the can.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the appended claims.
